To all t may concern:

Be it known that I, Louis BAUDENDISTEL, residing at Perryville, in the county of Perry and State of Missouri, have invented new and useful Improvements in Hullers, of which the follow-ing is aspecification.

My present invention 'has to do with hulling apparatus and has 'for one'of its objects the provision in a hulling apparatus of a cylinder and concave constructed with a view to breaking and removing thehulls of walnuts.

Another object of the invention is the provision in a hulling apparatus of meansv for separating the hul-ls and nuts and conducting the same separably out of the appara-tus.

Other objects and advantages of the invention will befully understood from the following description and claim when the same are read in connection with the drawings accompanying and forming part of thisspecification, in whicl1- Figure l is a longitudinal vertical section i of the hulling apparatus constituting the best practical embodiment of my invention of which I am cognizant.

Fig. 2 is a side elevation of the same.

Fig. 3 is a detail section on an enlarged scale illustrative of the arrangement of the hammer members and their appurtenances relative to the perimeter of the cylinder.

Fig. 4 is a detail plan showing the arrangement of the teeth on the concave.

Similar numerals of reference designate corresponding parts in all the views of the drawings.

Among other elements my novel .hulling apparatus comprises a main frame, 1, which is preferably, though not necessarily, of wood, and may be of any construction compatible with the purposes of the invention. "f

Su-itably fixed in the fra-me 1, is a concave 2 on which are teeth 3 arranged as illustrated and Adesigned to aiford abutments against which the nuts may be forced with a view to expediting the thorough removal of the hulls.

Leading to the said concave at the upper and outer end thereof is a feed trough 4:

which may be of the construction shown or of any other construction invention.

Mounted in suitable bearings above the concave 2 is the ,shaft 5 of the hulling cylinder 6. The said cylinder 6 is provided on its perimeter with Hap-like hammers 7. These withoutl affecting my Specification'of Letters Patent.

hammers 7 are preferably though not necess arily arranged in staggered relation on the cyl1nder,'and each is connected at 8 in a hinged manner to the cylinder. v

It will also be observed that each hammer is provided with a rod 9, arranged to extend loosely through an Vaperture in the cylinder wall and terminating within the cylinder in an enlargement 10; the purpose of said enlargement being to bring up against the cylinder wall when the hammer 'is thrown outwardly by centrifugal force and thereby limit the'outward movement of the hammer. Manifestly, while I prefer to arrange the hammers 7 in staggered relation as stated, I do not desire to be understood as confining myself to the same, inasmuch as other' arrangements of the hammers may be resorted to without involving departure from the scope of my appended claim; Springs 9a on rods 9 cushion the hammers 7.

Mounted to swing in a general longitudinal direction in the frame 1 and in front of the cylinder and concave is a shaking screen 11. The said screen is suspended on hangers 12 in the frame and is made up of rear and forward serrated portions 13 and a foraminous portion 14 dlspfosedv intermediate the portions 13. At its rear or inner end the screen 11 is provided with an upwardly extending flange 15 designed and adapted to assure the nuts and hulls assing from the inner and forward end of t e concave to the rear and inner end of the screen.

Disposed in the frame and below the inner serrated portion 13 of the screen is a fan casing 16 in which is a rotary fan 17, and leading downwardly and forwardly from said casing is a chute 18 which terminates at its forward end in a transversely disposed trough 19 the point of discharge of which is at one side of the frame. It will be readily noticed that the foraminous portion 14 of the screen 11 is disposed above the chute 18.

Journaled at 20 in the frame is a transverse shaft bearing acrank 21. The said crank 21 is connected through a pitman 22 with the rear and inner end of the screen 11 whereby rotation of shaft 20V will be attended by longitudinal reciprocation of the screen 11.

The cylinder shaft 5 is connected through gear 23 with the crank shaft 20, and it is manifest that the said shaft 5 may be mansuitable motor not illustrated.

In the practical operation of my apparatus the cylinder 6 is rotated in the direction indicated by arrow in Fig. 1, and incidental to said rotation the nuts to be hulled are fed through the trough 4 to a position between the cylinder and its complementary concave. As the cylinder is rotated in the direction indicated the hammers 7 are thrown outwardly and serve to strike the nuts against the teeth 3 of the concave with the result that the hulls are knocked oi' of the nuts. Subsequently to the breaking and removal of the hulls the nuts and hulls together are moved through the medium of the hammers 7 up the forward and inner portion of the concave and will be discharged upon the inner serrated portion 13 of the screen 11. This screen 11, being reciprocated serves to feed both nuts and hulls toward the discharge end of the machine, and when the nuts reach the foraminations 14 they drop through to the chute 18 and pass upon the chute to the trough 19 by which they are conducted out of the machine. In cidental to the passage of the hulls and nuts over the trunk of the fan casing 16 the blast of air afforded by the fan serv'es to free the nuts of dust and dirt so that they are in a clean and wholesome sta-te when received on the chute 18. The hulls and other debris are carried out of the machine and discharged into a: receptacle laced to receive them, or if preferred the ischarge may be into the fan casing 23 of a pneumatic stacker as illustrated.

In serving to move the nuts and hulls upwardly and forwardly on the inner and forwarrd portion ofthe concave the hammers 7 are adapted to move inwardly toward the periphery of the cylinder 6 with the result that there is little o-r no liability of the apparatus being choked at that point.

It will be gathered from the foregoing that my novel apparatus is simple and compact in construction, and is adapted to eX- peditiously and thoroughly free the nuts from the hulls, and this without injury to the nuts and without liability ofthe nuts being scratched or otherwise marred. It will also be gathered that the apparatus is well adapted to withstand the rough usage to which apparatus of corresponding character is ordinarily subjected.

Having described my invention, what I claim and desire to secure by Letters-Patent 1s: In a hulling apparatus, the combination with a concave having teeth with flat sides, arranged-in stepped Jformation thereon, of a cylinder spaced from the concave, flap-like hammers hinged to the perimeter of the cylinder and having flat heads opposed to the flat sides of the teeth and also having arcuate rods movable in apertures in the cylinder wall and provided at the inner side thereof with enlargements, and coiled springs on said rods and arranged between the cylinder and the hammers.

In testimony whereof I affix my signature.

LOUIS BAUDENDISTEL.
